Hexmag magazines are made from durable, lightweight polymer material and are designed to function perfectly in most AR-15/M4 compatible rifles. They feature a raised hexagon pattern for superior grip and secure handling, a USGI spec stainless steel spring and an anti-tilt follower. The tool-free latch plate design makes disassembly fast and easy. The Hexmag HexID color identification system makes ammo recognition simple.
